You could try what Al suggested and update that Focbox firmware to the latest version, then try running it through the new tool
FOCBOX_TOOL.zip (18.3 MB)
It would also rule out a bad usb cable/port if it works with the old tool

That was just the bootloader, either way throws the same issue
Same cable works on the Xenith so thatās not it, I will try that version though
The xenith would have had 23.46 on it from the factory.

Focbox tool put it to 23.46 so thatās good, it turned it off immediately after the firmware was updated

Two more things you could try -
The new BETA tool from the VESC site (had some updates around this stuff)
The old 3.01 tool

No luck with the 3.01, still canāt erase the bootloader
Does just running the firmware update do the same thing? Did the beta tool work?
Would probably need an ST-LINK v2 if these donāt work :\

Nah firmware update plays games and doesnāt actually work, beta tool same deal
Well one more thing you could try before getting an ST-LINKā¦
Manually downloading the firmware and uploading it through the custom tab. This bypasses the bootloader

Oh you have one! You will still need the file above, but follow these instructions
ST-LINK over the SWD port.
- Download the firmware .bin file for the hardware version you have
- There is a JST PH 4 pin port. It has GND, DIO, CLK and 3.3v
- Hook an ST-LINK v2 up to that port. Only use the GND, DIO and CLK pins. Have the battery plugged in. If you cannot plug in to the battery, then use the 3.3v pin as well, but this is not the recommended method.
- Plug the ST-LINK v2 into the PC
- Download the STM ST-LINK Utility
- Open and click Target ā Connect.
- Click Target ā Program & Verify
- Click Browse and load the .bin firmware file.
- Click Start.
- Wait 30 seconds then unplug the STLINK and the battery from the ESC. Plug in the ESC to the battery and connect through the normal USB port or bluetooth to configure with the VESC tool or VESC app.
EDIT: For the unity the SWD is on the black connector

Trying the manual download, it downloaded then froze the tool
Seems to have 5.03, I thought VESC Tool 6 had hw6.00 though?
Ope NVM we got v6.00 boys 
thank ya for the help

If you have multiple ESC flying around, you can go for the SWD Prog procedure. Basically you use a healthy unit to program a bricked unit via SWD.
You need to interconnect CLC to CLK, IO to IO and GND to GND. The cable should be rather short.
Watch at minute 5 onwards.
Another note on the side: VESC-Tool always updates the bootloader before flashing the FW.
SWD-Prog doesnāt upload a bootloader though.
